Free to fly with. Premium removes the limits.

Yes, and the part that matters most is free forever. Tracking your flight offline in Airplane Mode, the world basemap, live altitude, ground speed, heading, distance and ETA, the name of the city or sea below you, flight-number lookup, the landing countdown and the sun almanac all work without paying anything and without an account. The free tier saves your first 5 flights and shows ads.

Flights past your allowance are never deleted. SkyDot keeps recording and saving them — they sit locked in your travel log, and every one of them unlocks the moment you upgrade. Tracking itself is never limited either — SkyDot will follow every flight you take, whether or not you have saves left.

Yes. From the travel log you can watch a rewarded ad to unlock 1 more save, up to 2 ads a day and 10 bonus saves in total. That takes the free tier to 15 saved flights in all.

No. Lifetime is a one-time purchase of $19.99 — it never renews and there is nothing to cancel. Monthly and Annual exist for people who would rather not pay up front.

If you fly even a few times a year, Lifetime. At $19.99 it costs less than seven months on Monthly, and it is what the app itself recommends. Annual works out about 64% cheaper than paying monthly for a year. Monthly is the one to take if you want to try Premium on a single trip.

Monthly and Annual both start with a 7-day free trial. You are not charged during the trial. Unless you cancel at least 24 hours before it ends, it converts to a paid subscription and your store charges you then, and again at the start of each period after that. Lifetime has no trial because there is nothing recurring to trial.

Through your store, not through us — we cannot cancel a subscription on your behalf. On Android, open Google Play then Subscriptions. On iPhone, open Settings, tap your name, then Subscriptions. Cancelling stops the next renewal and you keep Premium until the period you already paid for runs out.

• Manage subscriptions on Google Play
• Manage subscriptions on Apple

Refunds are handled by the store you bought through, under their policy, not by us — we never see your card details and cannot issue a store refund directly. Google Play and Apple both have a request form, and both are usually quick about it.

• Request a refund on Google Play
• Report a problem with an Apple purchase

Prices shown are in US dollars. SkyDot is sold in 174 regions and your store sets the price where you are, so the amount you see may differ. It is not a conversion of the dollar figure: each store picks a round local number. In Pakistan, for instance, the app currently shows Rs 900 monthly, Rs 3,500 annually and Rs 4,900 for Lifetime.

Yes. One payment of $19.99, and Premium stays unlocked on that store account permanently, including every future update. There is no renewal, no second charge and no expiry.

Purchases belong to the store you made them in. Premium bought on Google Play unlocks on the Android devices signed in to that Google Account, and a purchase made on the App Store unlocks on the Apple devices signed in to that Apple Account. Buying on one store does not carry across to the other, which is how both stores work rather than a SkyDot rule.

Yes. Airplane Mode switches off the cellular and wifi radios. GPS is a receiver: it listens to satellites and transmits nothing, so it keeps working. Turn Airplane Mode on, leave Location on, and SkyDot tracks the whole flight.

No. Download the maps you want and set your route while you still have signal on the ground. Everything after that runs on your device.

GPS at cruise is modest, because the receiver is doing the work and the radios are off. A long-haul flight on a full charge is comfortable, and you can close the app and reopen it later without losing the log.

No, by design. SkyDot tracks your flight from your seat. It is not a plane-spotting app for watching other aircraft overhead. That needs a live data feed, which is exactly the thing that stops working at 38,000 feet.

No. Tracking works with no account at all. Google or Apple sign-in is optional, and only there to carry your travel log between devices.
